SIFTER.

SPECIFICATION forming part of Letters Patent No. 783,238, dated. February 21, 1905.

Application filed Tannery 20, 1904. Serial No. 189,782.

To (LZZ whom it may concern.-

Be it known that I, HARRY KANE BENDER, a citizen of the United Stat s, and a resident of Weehawken Heights, in the county of Hudson and State of New Jersey, have invented a new and Improved Sifter, of which the following is a full, clear, and exact description.

My invention relates to an improvement in sifters, especially ash-sifters; and the purpose of the invention is to provide a construction which will be dust-proof, and wherein the receptacle for the material may be operated without any escape of dust at the opening in the casing through which the operatingmedium for the said receptacle extends, and wherein all the operative parts of said receptacle may be readily removed in order that only the body of the sifter containing the dust may be conveyed to the dumping-ground or to a reservoir and its contents conveniently emptied.

Another purpose of the invention is to provide a sifter of the character above described which will be simple, durable, economic in construction, and effective in operation.

The invention consists in the novel construction and combination of the several parts, as will behereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference inclicate corresponding parts in both the figures.

Figure l is a vertical longitudinal section through the improved sifter, and Fig. 2 is a plan view of the sifter with the cover removed.

A represents the body of the sifter, which may be of any desired type, and the said body A is preferably in the form of a rectangular casing of greater length than width, and said casing is provided with a cover B, which is fitted to the body in a dust-proof manner. The body A is provided with a track 10 at its inner face at each side, and these tracks 10 preferably extend from the rear end of the casing to a point near its front end, as is illustrated in both Figs. 1 and 2.

A removable compartmentC is constructed at what may be termed the forward or front end of the casing above the tracks 10, and, as is shown, this compartment C consists of a front board 11, which extends down into the space between the front ends of the track and the front of the body, resting on the front sill 11, a rear board 12, and side boards 12,

which latter boards rest upon the tracks 10, so that the said compartment (J may be lifted from the body A whenever desired.

A slot or opening 13 is made in the front portion of the case, which opening or slot registers with a smaller slot or opening 13, having direct connection with the compartment C, being made in the front board 11 of the compartment, and a corresponding slot or opening 14 is made in the rear board 12 of the compartment C.

An agitating-bar D is made to pass through the said openings 13, 13, and 14, and this agitating-bar consists of a horizontal member 15, having sliding movement in the aforesaid openings 18, 18, and 14, and this member 15 of the agitating-bar is provided at its outer end with a handle 16, which handle is capable of passing through the front opening 13 in the body of the device, but cannot pass through the openings 13 and 1 1 in the walls of theremovable compartment 0.

In the further formation of the agitating-bar D a rear horizontal member 17 is employed, connected with the'forward member 15 by a vertical member or section 18, and at the rear end of the rear horizontal member 17 an upwardly-extending lip 19 is formed, the lip 19 being parallel with the intermediate upwardly-extending member or section 18, as is best shown in Fig 1 An ash-receptacle 20 is made to rest on the rear horizontal member 17 and is confined between the intermediate vertical member 18 and the lip 19, as is also best shown in Fig. 1, so that this receptacle 20 may be readily removed from the agitating-bar or from the body A when necessary. In the drawings this agitating-bar D is shown as having a horizontally-reciprocating movement in direction of the front and rear of the case or body; but I desire it to be understood that such agitating-bar D may be given a lateral movement or a lateral and end movement, or it may be given a rotary movement, as may be desired. When the ash receptacle or Sifter 20 is placed on the agitating-bar D, its side portions at the bottom rest upon and have sliding movement on the tracks 10. s

In order that dust shall not escape from the front openings 13 and 13 when the cover B is closed, I employ a flexible protector 21,

which consists usually of fabric, such as can vas, for example, and this canvas is preferably in conical form, the contracted end of the protector being secured in any suitable or approved manner-for example, by lacings 22-to the agitating-bar D, and at the wider end of the protector a wire ring 23 is located, so as to hold the Wider portion of the protector in open position. The wider end of the protector may be secured to the front boardll of the compartment C; but usually the flexible protector is located within an outer rigid casing 24 of corresponding shape, and this outer casing 24 is within the compartment C and at its wider or outer end is secured in any desired manner to the front board 11.

The inner end of the said casing 24:, which may be termed a protective casing, has bearing against the rear board 12 of the said compartment C at the opening 14 in said rear board, so that as the agitating-bar is moved to agitate the ash-receptacle 20 any dust which may escape through the opening 14 is prevented from escaping through the outer openings 13 and 13 by the interposition of the pliable protector 21.

An ash-sifter constructed as above set forth is practically absolutely dust-proof. It is exceedingly simple in its construction and can be operated expeditiously and conveniently.

When the operative parts are to be taken out from the body, the cover B is removed, and then the sifter 20. Next the compartment C is raised in a vertical direction until the lower portion of the front board is released and is entirely free from the restraining influence of the tracks 10, and when the rear end of the lip 19 of the agitating-bar D is practically above the sides of the body A the front member 15 of said bar may be drawn rearward, the handle 16 atsuch time passing through the opening 13 in the body or casing of the device, and when such condition prevails the agitating-bar Dand the compartment Cand parts contained therein may be removed from the casing or body A, leaving it and its contents free of the apparatus and enabling it to be transported and emptied wherever desired.

A stop 25 is located on the forward member 15 of the agitating-bar D, which limits the movement of the bar D with respect to the rear board of the compartment C. The body A may be made of any suitable material-as, for example, wood or metal.

I desire it to be understood that the flexible protector, with or without its casing, may be used in connection with any description of sifter.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. In a sifter, a case, acover therefor, aremovable compartment in the case in flat en- ,sifter and extending from the sifter through said compartment and also loosely through the wall of the casing, an elongated pliable protector within said compartment secured at one end to the agitating-bar and at the other end secured against the forward wall of said compartment, the agitating-bar having free longitudinal'movement in the case.

2.
